Abstract: A method for centralized mass processing of substitutable, good-holding magazines used in conjunction with computer-controlled vending machines. A memory-chip-mounting smart-card is used, not only to enter into the machines the magazine location and price of the various goods, but also to carry a sales transaction record of the replaced magazine, thus avoiding the need for magazine locking mechanisms and other security measures.

Abstract: An adjustable support structure for temporary sign displays formed from a vertically oriented rigid panel having a plurality of length and angle adjustable support arms. Each arm has a distal end thumb screw attachment to a T-nut on the sign. The arm is adjustably anchored to the panel by a bolt extending from the panel through a longitudinal oval slot in the arm to engage a wingnut. Additional hardware prevents loss of movable parts. Sign stiffening battens are tethered to the panel. A stiffening tray parallely spaced apart from the back of the panel further bears against and secures the support arms.

Abstract: An apparatus for unloading a carton or other package holding a set of cylindrical containers such as beverage cans or bottles, and for dispensing them, one-by-one in a horizontal rolling position into a vessel such as a vending machine magazine.

Abstract: A vending machine is housed in a light, yet sturdy enclosure made of an external sheet metal shell and an internal seamless plastic liner between which a volume of expanded synthetic foam material is injected. One or more good-holding magazines are removably held within the enclosure. A keypad, alpha-numerical display and card reader are packaged in the door closing the front of the enclosure. A driving motor module and a coin acceptor are removably mounted against the inside liner. Due to the absence of complex or delicate structure, the machine can be serviced, cleaned and sanitized within minutes. A pair of vending machine, one holding snack food, the other beverage cans are coupled to work together and dispense combinations of items from a single control panel. Both the beverage and snack food holding magazines are driven from the same type of motor module mounted inside the liner.

Abstract: A centralized method for selling items through a plurality of vending machines installed at various companies' sites comprises using vending machines having a substitutable goods-holding magazines from which goods can be extracted only when fully installed inside a vending machine and only by use of a special key when the magazines are outside their machines. The magazines are filled at the supply center and distributed along pre-established delivery routes. The servicing of each machine consists essentially of opening the machine, removing the previously installed magazine, substituting a new full magazine and securely locking the machine without any accounting of goods or currency or any other maintenance work.

Abstract: A light and compact vending machine suitable for use on a table or counter top, uses interchangeable magazines that can be preloaded with goods at a service center and quickly and conveniently installed on or removed from the machine. Each magazine has good-holding stations that differ in numbers and sizes. Each station has an access port on the front of the magazine toward which a spiral rack driven by a mechanism mounted in the machine moves goods. The currency accepted in payment for the goods is automatically dropped into a sealed receptacle at the bottom of the magazine. Each magazine is secured by a door that opens automatically only when the magazine is in place and the machine door has been locked. Personnel servicing the machine by replacing an empty one with a loaded one need not handle the goods or the cash. In some alternate embodiments of the invention, packaged goods and beverage cans slide down along slanted channels toward dispensing gates under their own weight.

Abstract: A set of simple and economical components is used to transform an existing back lighted sign into a self-propelled scrolling banner display. Only two structural parts are used, and the electro-mechanical components are limited to a step-down transformer, a rectifier circuit, a pair of motors, and a switch and voltage step-down diode assembly.

Abstract: A drilling template for carving into the lateral edge or the jamb of a door, a slot shaped and dimensioned to receive either a lock and its mounting plate or its strikeplate has a series of drill bit bores at regular spaced-apart intervals along a central line, a pair of lateral legs, and mounting holes corresponding to those of the lock or strikeplate. A drill is used to rout the lock blade slot through the drill bit bores. Guides in either side of the bores prevent lateral movement of the bit, but allow slight longitudinal swing to remove material that may remain between holes. The height of the guides may be varied along the length of the template to guide the routing for a slot of more uniform depth. Lateral spacers are provided to align the template against the angled part of the door jamb. A specialized routing drill bit is provided for drilling the strikeplate or lock channel. The bit has central pilot shaft for tracking within the lock blade slot and a removable circular toothed disk.

Abstract: In a banner display device where a plurality of banners are mounted end-to-end upon a carrier web to form a scroll which is wound on a pair of parallel and spaced-apart rollers, means carried on the scroll for stretching or decompressing a medial section of a displayed banner sufficiently to eliminate wrinkles and small distortions. One embodiment uses means for propelling the medial section away from the web comprising resiliently flexible banner end sections or resiliently flexible strips framing the banner which, when partially wound over the rollers, resiliently assume a more planar tangential position in relation to the rollers, thereby allowing the medial section to jut anteriorly away from the carrier.An embodiment further comprises two independent lateral support members capable of being mounted within enclosures having widely different widths. Components such as motors, transmissions, roller mounting spindles, control sensors and circuitry are mounted directly on the support members.

Abstract: A drilling template for carving into the lateral edge or the jamb of a door, a cavity shaped and dimensioned to receive either a flanged lock or its strikeplate has a series of drill bit bores at regular spaced-apart intervals along a central line, a pair of lateral legs with sharp ends, and mounting holes corresponding to those of the lock or strikeplate. The template is designed to be hammered into the door edge or jamb until the sharp edge-ended edges define the outline of the lock flange or of the strikeplate as well as the amount of wood to be removed to form the mortise necessary to nest those elements. The template can be screwed in place through mounting holes that correspond to those of the lock or strikeplate. A drill is used to rout the cavity through the drill bit bores. Guides in either side of the bores prevent lateral movement of the bit, but allow slight longitudinal swing to remove material that may remain between holes.

Abstract: A mechanism for the powered opening and closing of household panels such as windows and doors comprises a worm drive screw, small enough to be mounted within and along the upper track of a sliding panel. A nut threaded on the drive screw moves axially along the screw when the screw is rotated. Motion of the nut is transmitted to the panel by means of a coupling bolt, slidingly mounted within a cavity in the top of the panel. The bolt slides up to engage the nut for powered operation, and slides down to disengage from the nut during manual operation. The position of the bolt can be secured through locking means. A resilient, dielectric transmission accouplement between the drive screw and the motor provides electrical and vibrational isolation, and scalability. A second extendible bolt mounted on an opposite end of the frame hinders pitch deflection of the panel during powered operation. Worm gearing and a solenoid based brake locks the motor and the position of the nut when no power is applied.

Abstract: A non-lethal incapacitating device comprises a pair of projectiles and trailing wires packaged in a cartridge mountable on the head of a stungun. The cartridge assembly includes a pair of light and directionally stable and non-invasive projectiles having tubular plastic flares, expanded trailing wire coiled in double layers on a rotating magazine, a simple gas capsule side-piercing mechanism, and a compact housing.

Abstract: A banner display device where a plurality of banners are mounted end-to-end to form a scroll which is wound on a pair of parallel and spaced-apart rollers, each driven by a motor. Pulse code modulated drive voltages are produced by microprocessor based command and control circuitry to accurately and efficiently turn the motors at speeds which impart proper tensioning of the scroll during winding.

Abstract: A capsule loaded with a pressurized gas has a single front aperture sealed by an internal plug made of resilient material. The cartridge is loaded by placing it inside a pressurized chamber, then drawing the internal plug against the aperture before decompressing the chamber. A self-propelling embodiment comprises an expellable volume of liquid stored in the rear section of the cartridge in contact with its puncturable base, and separated from the pressurized gas by a floating piston. The base is concavely formed into a bell shape to focus the expelled liquid in a rearward direction.

Abstract: A cylindrical plug made of elastomeric material is introduced into a cylindrical cartridge. The rim of the cartridge is swagged-in to reduce the diameter of its opening to one-third of the cartridge internal diameter and of the closely matching plug external diameter. The cartridge is held in a chamber. A tube slidingly passing through the wall of the chamber comes in contact with the plug, and holds it within the container while the chamber is filled with a highly pressurized fluid. As the cartridge is filled with the pressurized fluid the plug is tightly held against the internal end of the tube. The tube is partially withdrawn drawing the plug against the swagged opening of the cartridge. As the tube continues to be withdrawn its internal open end is separated from the plug, and pressurized fluid begins escaping through the tube indicating that the cartridge is filled. The pressurized fluid can now be evacuated from the chamber.

Abstract: A device for displaying a scrollable banner wherein the single banner pick-up roller used in prior art devices is replaced by a multi-roller spool. Each multi-roller spool comprises at least two rollers connected with spool belts which define a winding area much longer than that of any single roller. The spools are rotatably mounted within a display housing. Motors drive the multi-roller spools. Additional features include: convex style crowned pulleys for automatically centering each of the spool belts, a centrally located roller separator mechanism which gives a convex crown structure to the entire spool itself whereby the banner is automatically centered, and a display housing of far reduced depth.

Abstract: A scroll displaying mechanism suitable for use in moving advertising displays, chart recorders and tape readers uses a pair of D.C. motors wired to operate under slightly different speed-controlling voltages in order to maintain the displayed part of the scroll between two rollers taut. A simple belt and pulley drive mechanism for each roller assures quiet and vibration-free operation. The viewing time between frame-advance and the scroll direction reversal are controlled by detection of different length markers positioned along one edge of the scroll. Also disclosed is a simple, easily assembled and disassembled display apparatus which allows both vertical and horizontal adjustment of the size of the viewing window frame.
